Food Webs Within Ecosystems
Marine, Freshwater, and Terrestrial FOOD WEBS Ecosystems A
community of organisms interacting with one another and their
environment Includes all Biotic and Abiotic factors Biotic Factors
All living things Plants and animals Abiotic Factors All nonliving
things Water, light, air and land Marine Ecosystems Oceans
Freshwater Ecosystems
Lakes, ponds, rivers, streams Terrestrial Ecosystems - Land
Forests, Deserts, Grasslands, Mountains Place where an organism
lives
Habitat Place where an organism lives Group of individuals of the
same species that live in a certain area
Population Group of individuals of the same species that live in a
certain area Species A group of similar organisms that can breed
and reproduce offspring. All the populations that live and interact
with each other in an area
Community All the populations that live and interact with each
other in an area The role of an organism within its community
Niche The role of an organism within its community Coral, plankton,
fish Food Chain Shows how the energy in food is passed from
organism to organism in an ecosystem Food Web Combination of all
overlapping interconnected food chains in an ecosystem. Producers
Organisms that get energy from the Sun
through photosynthesis - Plants Consumers Animals - Organisms that
eat other organisms
to obtain food for energy 3 Types of Consumers Herbivores Animals
that only eat plants
Omnivores Animals that eat plants and other animals Carnivores
Animals that only eat other animals (meat) Predator/Prey
Relationships
Predator Organism that hunts, kills and eats another organism Prey
Organism that is hunted, killed and eaten Parasite/Host
Relationships
Parasite organism that feeds off other living creatures Fleas,
Ticks, Worms, Lice, etc. Host organism that is being feed on by a
parasite Decomposers Organisms that get their energy by breaking
down dead organisms and other organic matter Video Quiz What is the
